Vacations

Jen Selter put her best assets on display in Mexico this week ... and TMZ Sports has the pics!!!

The 25 year old uber-popular fitness model (she has almost 13 million Instagram followers!!) put on a pink bikini and hit the beach in Cabo San Lucas ... and braved the waters for an impromptu photo shoot.

We're told Jen spent the past couple weeks on vacation in Mexico with her mom and sister ... but, as you can see, she took a break from her break to hit the beach for some snaps.

Selter's known to take her booty on tour around the world -- from Greece to Mexico to Miami -- and this batch is sure to heat you up during the polar vortex.

Enjoy!!!

12:55 PM PT -- A rep for Gwyneth tells us, "This lawsuit is completely without merit. Anyone who reads the facts will realize that."

Gwyneth Paltrow allegedly doesn't know the rules of the road mountains in Utah -- 'cause a guy claims she crashed into him during a ski trip and seriously jacked him up.

Utah resident Terry Sanderson just sued Paltrow -- as well as Deer Valley Resort -- where he claims the actress slammed into him in February 2016 as he was skiing down the mountain.

In the docs, obtained by TMZ, Sanderson says Paltrow was out of control as she hit him from behind, which knocked him over and left him in shock. He claims she simply got up, didn't say a thing, and kept on going while he was left lying there.

Sanderson also claims Paltrow knew that a downhill skier usually has the right of way on a slope, and that he was clearly downhill from her.

He goes on to claim that a ski instructor who was tailing Paltrow stopped off and accused Sanderson of causing the collision, allegedly asking, "What did you do?" ... and skiing away without getting help for the guy. Sanderson alleges the instructor also filed a false report casting blame on him in an attempt to protect Paltrow.

He says he suffered a concussion, a brain injury and four broken ribs -- going on to claim he's suffered physical and mental injuries, loss of enjoyment of life, emotional distress, disfigurement and medical expenses.

Sanderson is asking a judge to award him damages in excess of $3.1 million.

Blac Chyna's Hawaiian holiday went to hell fast, after paramedics and cops showed up at her hotel because of a physical fight between Chyna and her new boyfriend ... TMZ has learned.

We're told at around 5 AM, Chyna and Kid Buu were in their hotel room at the Ritz-Carlton in Honolulu when they got in a heated argument. We're told Chyna accused Kid Buu of cheating, and just before 7 AM it turned violent.

We're told Chyna scratched Kid Buu, and our sources say he then slammed her against the wall several times and choked her.

Someone called 911, and cops and paramedics arrived on scene.

Chyna was not taken to the hospital and, as far as we know, no one was seriously hurt.

As for Kid Buu, he left the hotel and posted in Spanish ... translation -- "Don't f**k with me, I'm a grown man." He followed it up with a homophobic slur.

Jake Owen and Luke Bryan are a little bit country and little bit surfer dude -- at least for this weekend -- while they're partying on la playa in Mexico.

The country superstars attempted to catch some waves -- on paddleboards, not surfboards -- in Tulum, near Luke's annual Crash My Playa festival is going down. Looks like Jake had a little more luck than Luke ... but only a little. Hey, they're Nashville bros ... no one's expecting them to hang ten.

Luke's wife, Caroline Boyer, and Jake's GF, Erica Hartlein, hung out on the beach while the guys tried their best to look epic on waves.

In the evening, they returned to their natural habitat ... rocking the stage for the 4-day festival. Luke tried a one-handed floss move while playing, "All My Friends Say."

Good times. Although, not as good as what went down during last year's festival when he got whacked by a fan's bra. A REALLY big bra. 'Memba that?

As Luke puts it ... strip it down!!!

Ansel Elgort and his high school sweetheart escaped the bad L.A. weather over the weekend with a trip south of the border ... where they both gave off muy caliente vibes.

The "Baby Driver" star -- who'll soon be the new "West Side Story" star -- was spotted hitting a beach in Mexico Sunday with his longtime girlfriend, Violetta Komyshan ... and they both looked incredible in their swimwear as they packed on the PDA.

Ansel was also sporting a new 'do -- bleaching his normally brown hair blond, and definitely pulling it off too. Violetta, of course, looked hot as hell too au naturel.

The couple has been dating since their high school days at Fiorello H. LaGuardia School in NYC -- and they've been going strong for seven years ever since.

The guys from "Riverdale" are definitely enjoying their mid-season break right now -- and it looks like Archie's still in tip-top shape without a shirt on. Ditto for Jughead!

KJ Apa -- who plays Archie -- and his right-hand man, Cole Sprouse, were spotted enjoying a day at a lake this week down in New Zealand, where they stripped down and took a much-needed dip.

We say much-needed because fans of the TV show are anxiously waiting for season 3 to continue. For now, these hot shots are gonna have to quench their thirst.

In the mid-season finale of "Riverdale" ... Archie was also shirtless and kicking some serious ass in an underground fight club at a juvenile detention center, from which he escaped.

If this outing is any indication, KJ will hopefully stay topless through the rest of the season when the show returns later this month.

Couple Chris Pratt and Katherine Schwarzenegger are showing more signs they're heading for some sort of union.

Chris and Katherine were hanging out Saturday at a swanky Cabo San Lucas resort. That's nothing earthshaking until year see who they were with.

They traveled south of the border with Katherine's mom, Maria Shriver and Katherine's brother Patrick Schwarzenegger, along with a few other family members. No sign of Arnold Schwarzenegger, although he's also spent time with Chris.

As we reported, Chris also hung out with Katherine's fam during Thanksgiving.

Chris and Katherine started dating last Summer.

If Jon Bon Jovi's voice ever craps out, we found the perfect stand-in ... a guy who already knows all the lyrics, and is usually just a few feet away onstage -- his keyboardist, David Bryan!

David walked into the Casa Nightclub in St. Bart's Wednesday around closing time -- 5 AM (island time, mon) -- with some friends. The DJs -- Shortkutz and Chris Magic -- recognized the Bon Jovi rocker and started blasting the Hall of Fame band's hits.

DB must've been feeling real good because he jumped up and grabbed the mic to belt out "It's My Life" and "Livin' on a Prayer."

Folks at Casa tell us the club's owner, Julien Roussel, decided to stay open a little later so the patrons could enjoy the free concert and keep singing along.

David sang 5 of the band's hits when it was all said and done before waltzing out of the joint.

BTW ... Bon Jovi goes on tour in May, but we're pretty sure Bryan will be back on keys and backup vocals. For now.

Jared Leto's surrounded by a throng of bikini-clad women on a Caribbean island ... and it's pretty clear he's the straw stirring the drink.

The "30 Seconds to Mars" frontman was cruising on a yacht Wednesday in St. Barts with a bunch of very eye-catching friends ... including several women in bikinis and some ripped dudes. It's in the 80s down there -- like always -- so they're feasting on some Vitamin D.

Jared and co. came ashore to stroll the perfect white sand beach and snorkel in the crystal clear waters.

He shoots, he scores ... ON WATER!!!

Michael Jordan's 2019 is off to a GREAT start -- he's hanging out on an $80 MILLION super yacht off the coast of St. Barths ... and the ship has a basketball court onboard!!!

Seriously ... this thing's amazing.

Unclear if MJ is ponying up the $840,000 per week it costs to charter the 230-foot floating mansion -- but he's reportedly worth around $1 BILLION, so it's not like he can't afford it.

Either way, this ship is paradise on water -- with 8 cabins, a bar, dining room, full gym, deck Jacuzzi ... and, oh yeah, the basketball court!!

The yacht also boasts a state-of-the-art audiovisual system, satellite TV and fast WIFI ... so you can still check your Instagram from the middle of the ocean.

Katie Holmes and Jamie Foxx are on the waterfront ahead of New Year's Eve -- and on the issue of jet skis ... Katie's leading the charge into battle.

The couple mounted some WaveRunners Saturday in Miami, and made a splash cruising around Biscayne Bay ... where Katie served as the pilot, and Jamie her trusty #2. She was ahead of him for most of the ride, and really seemed to have a handle on things.

KH and JF have been in Florida on a romantic getaway since at least Friday, where they've been staying in a luxury yacht ... just the two of them, as far as we can tell.

Going out as a couple has been a gradual progression for them since last September, when they first went public with their longtime relationship. Since then, they've been seen out together more and more ... and this is just their latest display of being boo'd up.

Scarlett Johansson and Colin Jost have a hell of a weekend update ... PDAing in Argentina's capital city the day after Christmas.

The 'Avengers' and 'SNL' stars are in the touristy town of Palermo in Buenos Aires. They were total normies ... sightseeing, holding hands and walking arm in arm. It seemed pretty intimate ... nevermind their bodyguard.

The couple spent Xmas weekend in El Calafate, where they took in the massive Perito Moreno Glacier ... a must-see when visiting the southern part of Argentina.

As we first reported ... Scarlett and Colin started dating back in June 2017 and things really heated up during a romantic dinner a couple weeks later.

Mark Wahlberg's beach bod is the gift that keeps on giving the whole year.

The "Instant Family" star is enjoying the holidays with his family in Barbados at the Sandy Lane Hotel, and hit the Caribbean sand Wednesday for some Boxing Day fun in the sun and a cool dip in the sea.

Mark's muscles are already an eye-catcher, but even more so when matched with his colorful trunks and cross necklace bling.

Scott Eastwood had a very up close and personal run-in with a couple killer whales while paddle boarding down in Mexico -- and while it's incredible to see ... it's also kinda scary.

Clint Eastwood's son posted a video of himself out in the waters of Baja California Sur, where he says he and a pal stopped for lunch before paddling out to sea after hearing some orcas in the water.

Scott says they thought the wild beasts had disappeared by the time they got out there -- but, apparently, some whale noises and splashing around made 2 orcas circle back ... and, boy, did they get close. Check out the clip -- Scott and co. could've touched 'em if they wanted.

It's a majestic scene for sure, but ya gotta wonder how risky the dip with the whales really was. While orcas aren't known to attack humans ... it's always a possibility they could.

David Guetta showing off his abs and his hot bikini-clad girlfriend would normally be enough to focus on, but then his GF busted out a crazy diamond that's gonna get everyone talking ... ENGAGEMENT!!!

The EDM superstar and actress Jessica Ledon hit up Miami Beach Monday with their French bulldog. DG rocked his hard physique while she strutted in a blue bikini ... curves on full display.

She kept it classy too ... accessories around her neck, wrists and, of course, that ring finger.

David and Jessica haven't announced anything, but that ring's sure to set off a bunch of alarms. For what it's worth ... the ring looks like a doozy.

Farrah Abraham knows a match made in heaven when she sees one -- and it ain't in a boxing ring ... it's her butt and a remote sandy paradise.

The 'Teen Mom' star's extended vacay in the Maldives doesn't require much in the way of clothing --she's rocking a severely bare minimum white crocheted bikini here. Farrah jetted off to the islands last weekend with her daughter after backing out of her celebrity boxing match with Nicole "Hoopz" Alexander.

Farrah trash talked promoter Damon Feldman but, as we first reported ... she's got a new offer from "Teen Mom 2" star Kailyn Lowry to get in the ring.
